winsun new materials, a chinese company based in suzhou, china, has managed to print 10 full-sized eco-friendly houses in just one day. measuring 200 square meters and costing $4,800 USD to build, each dwelling was created in under a few hours entirely out of recycled construction and industrial waste with an enormous 3D printer. instead of using bricks and mortar, the system extrudes a mix of high-grade cement and glass fiber material, layer by layer, similar to traditional rapid prototyping processes. using CAD for the architectural plan, calculated tracing paths consider insulation materials, plumbing, electrical lining and windows, which can later be outfitted once the rest of the structure is assembled.

Watching the giant 3D printer squirt out cement and build up these trusses is just amazing. More photos at Designboom
